To all 'whom t may concern: n

Be it known that we,fLoU1s E. LAURENT and JAMES C. PATTERSON, citizensof the 'United States, and residents, respectively.,

.which carry the filling material, which trestlc subsequently becomesburied in the filling materialiand so lost for further use. Thispractice obviously is a very slow and expensive one on account of thetime required in building the trestle and the cost of material andlabor. lt has therefore been an object of our invention to provide anapparatus by means of' which building may be accomplished much moreexpeditiously and economically than 'heretof'ore. paratus comprising asits main elements, an incline trestle mounted on wheels for movementalong a railroad track and having `a trackway thereon for dumping cars;a conveyer in sliding telescopic connection with said trestle ttorreceiving the filling material from the dumping cars and discharging thesame in advance ot the trestle, the said trestle and conveyer beingmovable along the track one relatively to the other as the workadvances; means iu advance ot the conveyer for holding the1 railssuspended in the plane of the road-bed preliminary to the filling in oi"the latter; and means, such as a laterally swinging chute, 'forreceiving the material from the conveyer and discharging it in positionto till in the required width of the road-bed beneath the suspendedrails.`

Referring now to the accon'ipanying drawings forming a part of thisspecification-a Fig. l is a side elevation of an apparatus embodyingourinvention in working position on a railroad track and showing theVrailroadv This object is attained by an ap-` conveyer extended'inadvance ot'l the trestle substantially its full length.

Fig. 10 is a plan of' the same.` 4 Similar reference characters indicatelike parts in the several figures of'thedrawings. The movable trestle,indicated generally by A", may be of any suitable construction,"

the same preferably and, as here shown being made up of open or skeletonframe work in usual manner. This trestle is mounted on wheels formovement along a surface track or railroad, and when adapted for work ona double track as hereshown, is provided at its rear end with twopalrsof flanged wheels l0. 10, and lli, l1, `mounted respectively on axles l2and 13, journaled in suitable bearv ings at the under side of thetrestleuframe." The two sets-of rails forming the vdouble track on whichthe trestle stands are indicated at le and 15, andas the distancebetween the centers othese tracks vary more or less, one of the saidpairs of' wheels,` that indicated at l0, are rigidly attached lto theirsupporting axle in order to hold the trestle laterally on the track,while the other pair, l1, are'forinedV with double flanges `for, eIn`bracing the tracks and looselyl mounted on Gif) their supporting axlefor endwise adjustment whereby they will automatically accommodatethemselves to any variation between track centers.

is these two pairs ofwheels at the rear end of the trestle aresuiiicient to steady the latter and hold it against lateral tilting, wepreferably employ only one pair of wheels adjacent the forward end ofthe trestle, as indicated on l0 and 1i in Fig. t, both of which aredouble flanged and one, l0', being fixed to the axle, and the other,il', being loose on the axle for endwise adjustment to any variationbetween tracks, as

described in connection with the` adjustable' rear wheels ll.

r)The trestlc A is formed with an incline 20, terminating at its upperend in a lesser incline 2l, at the dumping point. Supported on theincline 2O is a double track 272-23 which at its lower end is arrangedin substantial alignment withv the road or surface tracks and at upperend merges into a single centrally arranged track 2li, whereby dumpingcars, such as indicated at D, may be ldrawn up one track on. the inclineto a dumping position on the central track 2e, and, after being emptied,be returned down the incline on the other track, this switching of thecar to the opposite track on the incline when returned as an empty beingcontrolled by a suitable switch S. By having this doublek trackvandswitch on the movable trestle, we avoid the necessity of having a switchin the surface track which would have to be relocated from time to timeas the apparatus is moved forward during progress of the work. rlheresulting saving in time and expense is obviously very substantial.

Coupled to the rear end of the .trestle A is a trailer T, which is inthe forni of an incline mounted on wheels 26 and having rails 27 thereonin alignment with those of the trestle and those of the surface tracks,which rails terminate at their lower ends in tapered shoes or points28,resting directly on the surface rails and having side flanges 29, 29,loosely embracing the latter, as shown in Figs. 7 and This trailer,which is loosely coupled to theV trestle by any suitable means, such asthe links 30, is forthe purpose of shorteni -g the trestle and adaptingthe saine where it oins with. the'surface track to any irregularitiesin the latter.

Also, by reason of .its trailing directly `on the surface tracks, thenecessty forbreaking joints in the latter as the apparatus. movesforward is avoided. n l

rihe Vfilling material carried on to. the trestle .by the. dumping cars,is discharged from the `latter into` a hopper'l-l attached to the.trestle `below the uppercentral track .24, as best shownrin ll, kand iskdelivered therefro .onitova `conveyor ,C supported `in.

a position directly below the same, by which it is carried to a point inadvance of the trestle where the road is being built. This conveyer,which may be of any suitable type, is here shown in the form of anendless belt operating over end rollers 35, 35, and intermediate idlersmounted on a. suitable frame 37, which latter has a sliding telescopicconnection with the trestle frame by resting on guides or rollers 38therein, as most clearly shown in Figs. 4 and 6. ln connection with thisendless conveyer we employ a belt tightener (not shown) such c as isused in general practice.

. The conveyer frame 37 at .its front end extends forward of the trestleand is mounted on flanged wheels 39 which rest and operate on thesurface tracks like the front wheels i0 and ll of the trestle,hereinbefore described. With this described arrangement of the trestleand conveyer, the latter, which is preferably made of considerablelength, is gradually drawny forward through the trestle as the workprogresseanntil its rear end reaches a positionl adjacent to the hopperIl. in the trestle, as shown in Fig. l', at which time the trestle isadvanced relatively to the conveyer and telescoping the same, as shownin F ig. 2. During such adjustment of the trestle relatively to thecon'- veyer, the latter is of course held stationary by suitablefastening means, such, for instance, as clamping means (not shown)connecting it to the track. As the conveyer frame is advanced beyond thetrestle, it is 100 adapted to be supported at proper intervals on thetrack by suitable means, such, for instance, as the wheels or rollersshown in Fig. l.

The conveyer at its front end is slightly 105 elevated as shown, inorder to deliver the material carried thereby into a raised hopper H,which latter in turn discharges into a chute E, mounted for swingingmovement in an arc across the line of the road, as inl110 dicated by thebroken line in F ig. 3, for the proper distribution of the material. Thehopper l-l and chute E are both supported on the front end of theconveyer frame, the

hopperbeing stationary and the chute being carried by a vertical post 45mounted for rotation in a step-bearing e6, ln some instances where itmay be desired to increase the radius of distribution beyondA that forwhich the swinging chute 'E is adapted, we 12o may providea supplementalconveyer of the desired length, suchy as indicated at C in Figs. 9 and10, .which will be of thesame orsimilar type as :that ofthe mainconveyer. This supplemental conveyerv may. be supported in any suitablevor .usual manner, the sameas here shown beingv connected lat its innerend with the conveyer frame andatits outer endwith a. swinging booiny,47, which latter is supported by..suitable'rigging R. 130

von a platform 48 at the front end of the conveyer frame. Thismay beaccomplished by a driving belt i9 connecting the enginedrum with theadjacent conveyer pulley 35.

as shown. Where the supplemental conveyer is used, this may be similarlyoperated from the engine drum thro-ugh a belt 50.'

The dumpingl cars will also be operated from the same power plant bymeans of a hauling rope 55 winding on a drum 56 driven by the enginethrough a belt 57. This hauling rope will have a hook or like means fordetachable connection with the car so that as one car is hauled up theincline and subsequently lowered asan empty, the rope may bedisconnected therefrom andv connected to a filled car on the oppositetrack.` Also, when the trestle is to be advanced in its telescopicconnection with the conveyer, as from the position shown in Fig` l tothat shown in- Fig. 2, the same engine will be utilized for thisy bysimply connecting the hauling` rope with the trestle at some convenientpoint thereon. l/Vhen the conveyer is to be advanced7 this also may be'accomplished uby the engine P through the medium of a rope and tacklel(not shown) connecting` with some'stationary object in usual manner.

Carried on the front end of the conveyer frame are suitable booms andrigging for laying tracks in advance of the apparatus as the filling inof the road-bed progresses. A. block and tackle M carried by a boom 60is'utilized to hoist a rail, as 6l, after which a loose rope 62 running'through a blockv 63 on the boom 60, is fastened to the end of the rail.The latter is then located in the plane of the road-bed with one endresting on a tie and its opposite end suspended over the space to befilled, asl shown in Fig. l,

-l after which the rope 62 is tightened to support the end of the railand the block and tackle M is disconnected therefrom, Ias shown in Fig.2. A clear space is now provided for the operation of the chute orsupplemental conveyer in distributing the filling material. After theill has been completed to the end of the rails or some distance inadvance thereof, ties are placed beneath the said rails, after which theconveyer is again advanced the desired distance for continuing the work.Inthis way we are enabled to completely build the'road iny advance ofthe apparatus and then advance the latter ,overy such "rondas the workprogresses. l i v l l.
